It's refresh rate for vertical and horizontal is around 30-83hz and have no displayport. I also have an EVGA 670 FTW and it has a displayport on it.

Now I am not super familiar with displayport but right now I am using a DVI cable and the max refresh rate I get is 60hz. If I use a displayport->DVI cable would that allow my refresh rate to go higher as it says on the monitors page on newegg? Also would there any benefits to use that cable in terms of anything?(power,color, anything)

Displayport is a new thing to me and I'd like to experiement but I'm more curious about the refresh rate.

Using a display port cable will not allow a higher refresh rate as it is sending the same digital signal to the monitor - lowering your resolution (usually to 800 x 600) will allow that higher refresh rate - most monitors don't have the ability to overclock the refresh rate or force a higher one at native resolution.
